Description

Waste liquid collecting assembly, sampling equipment and sampling reaction device Technical Field The invention relates to the technical field of experimental equipment, in particular to a waste liquid collecting assembly, sampling equipment and a sampling reaction device. Background Along with development of biological fermentation, in order to monitor the experimental process, a multiple sampling mode is generally required to detect parameter indexes in the reaction process, in the sampling process, a reaction reagent can remain in a sampling tube after sampling, the residual reagent must be removed cleanly during resampling, and a sampling pipeline and a sampling needle head are cleaned, otherwise, the effect of sample detection can be affected. However, in the prior art, the problems of discharging and collecting the redundant waste liquid and the cleaning liquid in the sampling tube are less studied, and the waste liquid collecting device is not particularly arranged in the reaction device, so that the waste liquid is usually collected by holding an additional container when the waste liquid is required. For example, chinese patent document CN208420441U discloses a quantitative sampling device for a reaction vessel having only a sampling device and no waste liquid collecting device. Chinese patent document CN218674376U discloses a liquid collecting device and a sampling apparatus, in which a driving assembly is connected to a collecting tube seat, and under the action of the driving assembly, the collecting tube seat can move in a horizontal direction, so as to drive a waste liquid collecting container and a sample collecting container to move in the horizontal direction. The device is only applicable to single sampling, if need the sample collection container on the collection tube seat to take a sample many times, if need higher human cost if manual replacement needs extra special mechanical structure of design if mechanical replacement. Chinese patent document CN115072086B discloses a rotary-disc type automatic sampling device, in which reagent bottles are both sampling bottles and waste bottles, and the redundant samples after sampling are required to be additionally sampled.
